Picturesque dragonet, Synchiropus picturatus, is a brightly colored member of the dragonet family native to the Indo-West Pacific: Philippines, eastern Indonesia and northwest Australia. It occasionally makes its way into the aquarium trade, where it is commonly known as the spotted mandarin, psychedelic mandarin or target mandarin.
Description
The picturesque dragonet may grows to a size of 7 cm in length. They have thick slime on their skin that inhibits many types of parasitic infection and minimizes the risk of disease following stress or physical trauma. This seems to help protect them from some other more aggressive fish.
The fish Synchiropus picturatus is one of only two animal species known to have blue coloring because of cellular pigment, the other being the closely related mandarinfish (S. splendidus). The name "cyanophore" was proposed for the blue chromatophores, or pigment-containing and light-reflecting cells. In all other known cases, the colour blue comes from thin-film interference from piles of flat, thin and reflecting purine crystals.[1]
Relationships to humans
The picturesque dragonet is a reef dweller, and so a reef-like environment is ideal for them. Natural feeding habits entail constantly browsing the substrate for copepods and other small invertebrates. Systems with an additional refugium are ideal, as these can help to generate suitable levels of food organisms as it prefers to peck on live rock. Because of this it can be a hard fish to keep.
It can, however, be weaned on to frozen food such as Mysis, Artemia and other prepared foods but these alone are unlikely to sustain them, particularly if it is having to compete with other tankmates.
The picturesque dragonet is peaceful and does better with peaceful tankmates, such as seahorses.
